    index: Cell<Option<u32>>,
    pub(crate) parent: &'a Node,
    prev_sibling: Option<&'a Node>,
    pub(crate) next_sibling: Option<&'a Node>,
    pub(crate) tree_connected: bool,
    pub(crate) tree_is_in_a_document_tree: bool,
    pub(crate) tree_is_in_a_shadow_tree: bool,
}

prev_sibling: Option<&'a Node>

The previous sibling of the inclusive ancestor that was removed.

next_sibling: Option<&'a Node>
